It's definitely possible to detect this cheat, just like money hacks. If you're using vars correctly you will be able to prevent this. Use a var if you are teleporting a vehicle yourself (like SetVehiclePos) and setting vehicle health, and reset that var after that. Meanwhile, run a timer that checks huge distances between vehicle respawns, and if the var is 0, put the car back to old position.

It's not 100% accurate but you will definitely be able to prevent this cheat a lot.
